The invention aims to provide an exceptionally simple and inexpensive, yet an eificient and desirable cup plate (hereinafter termed a thimble) for contact with a wall, floor or ceiling around an opening through I y j welded brackets 19 to the outers'ide of the 5 plate .10 and is. spaced outwardly from and disposed in concentric relation with the opening 1-2-,'leavin g a flat area between the open 'ing and collar adapted to abut an .end'of the 6 which a. pipe passes, the thimble being adapted to receive the end of a tubular insulator surrounding the pipe. Provision is made whereby the thimble is held against the wall,

floor, ceiling or the like, and the pipe insulator merely slides within the thimble incident to expansion and contraction.

The thimbles T and T? are of slightly different construction, and the thimbles T and T may be considered as following either or both of the structures used in constructing said thimbles T and T The thimbles T and T embody certain generic features of construction which will ofadditional structural features possessed by the thirnble T To this end, 10 denotes a circular plate having a laterally turned edge 11 to lie against a wall, ceiling. floor or the like,

'The'c o'llar'18 is formedof substantially semi-cylindrical sections 20'and '21having plain ends overlapped circumferentially and secured together by screws 22. By'removing these screws and the screws'17, the. two' sections of the thimblejmay be disconnected allowing easy application'ofthe 'thimble after passageof the pipe through the 'openingin the floor, wall, ceiling or the like, and when sai'd screws are reinserted, the de- 7 vice willbelfirmlyheld inv assembled con- 'dition.g 1 The'plate sections 13 and 14: of thimble T are formed with openings to receive anchoring wires or strips 23, and for illustrative purposes, one' plate section is shown provided with an elongated'slot24 whereas the other is "formed with ,a sinall o enin -'25,.

1. A pipe insulator cup plate comprising a plate'radiall'y dividedinto sections andadapted to lie against a wall, floor or ceiling, said plate having a'pipe-receiving opening and a flat area around said opening adapted to abut one endof a tubular pipeinsulator, a cylindrical collar projecting outwardly from said plate in concentric relation with said opening,

spaced outwardly from said opening and surrounding said area, whereby said collar is adapted to surround said end of the tubular pipe insulator, said collar being formed of arcuate sections, and means for securing said plate and collar sections in assembled relation.

2. A pipe insulator cup plate comprising a plate adapted to lie against a floor, wall or ceiling, said plate having a pipe-receiving opening and an area around said opening adapted to abut one end of a tubular pipe insulator, said platebeing divided diametrically of said opening into two sections having inner edges which directly abut each'other, a cylindrical collar projecting outwardly from said plate in concentric relation with said 'opening and spaced outwardly from the lat ter around said area to surround said end of the tubular pipeinsulator, said collar being formed of two substantially semi-cylindrical sections, said collar sections being secured to said plate sections respectively and having plain ends overlapped circumferentially, and

I removable fasteners securing said plain overlapped collar section ends together.

3. A pipe insulator cup plate comprising a plate adapted to lie against a floor, wall or ceiling, said plate having a pipe-receiving opening and an area around said opening adapted to abut one end of a tubular pipe insulator, said plate being divided diametrically of said opening into two sections having straight inner edges which directly abut each other, a cylindrical collar projecting outwardly from said plate in concentric relation with said opening and spaced out- Wardly from the latter around said area to surround said end of the pipeinsulator, said collar being formed of two substantially semiuate sections, and means for holding said plate, collar and sleeve sections in assembled relation, said sleeve sections having openings near their free ends to receive anchors for holding the plate against a wall, floor or ceil- 111g.
